Photovoltaic (pv) power generation has unique advantages in the field of new energy

Photovoltaic (pv) power generation has economic advantages can look from the two aspects of solar energy utilization efficiency. One is the inexhaustible solar energy, unlimited, and when receiving solar energy does not impose any 'tax', can be anywhere access; Second, in the current technical development of water

photovoltaics has economic advantage of solar energy utilization efficiency can be in two ways. First of all, the solar energy is inexhaustible, inexhaustible, when to accept solar, can be used anywhere, without any 'tax'. Second, the current technology development level, some solar energy utilization has become the economy. With the development of science and technology and breakthrough of the human development and utilization of solar energy, solar energy utilization of economy will be more obvious. If the 20th century is the century of oil, then the 21st century is the century of renewable energy ( The century of solar energy) 。 From the perspective of the construction cost of solar energy photovoltaic power station, with the large-scale application of solar photovoltaic power generation and the promotion, especially in mature industries and upstream silicon photovoltaic power generation technology, building roof and exterior wall compound exploitation platform. Solar energy is an inexhaustible, inexhaustible renewable energy, have a large number of available energy. Solar energy is about 1 per second launch. 6 x 1023 kw, which reach the earth's energy up to 8 x 1013 kw, 6 x 109 tons of standard coal. According to this calculation, the amount of solar energy reaching the earth's surface in a year of standard coal, equivalent to about 189. 2 billion t 10000 times is the world's major energy reserves. The service life of the sun is still at least 4 billion years. Compared with the human history, solar energy will continue to supply to earth's time is infinite, it determines the development and utilization of solar energy will be an effective way to resolve the shortage of conventional energy and dried up. The environmental pollution-free clean energy such as solar and wind energy, tidal power, in the process of development and utilization of almost don't produce any pollution, reserves is infinite, is the ideal alternative energy sources. Because the traditional fossil fuel ( Coal, oil and natural gas) In use process produces a large amount of toxic and harmful substances, causing serious pollution of water, soil and atmosphere, the greenhouse effect and acid rain formation, which cause serious damage to human survival environment and health, developing new clean alternative energy sources is imminent. Solar energy as a relatively ideal clean energy, more and more get the attention of the countries all over the world.
